SPECIFICATION forming part of Letters Patent No. 397,315, dated February5, 1889.

Application filed June 2, 1883. Serial No. 275,817. (No model.)

To all whom if may @n/cern:

Be it known that I, ASAHEL M. SHURTLEFF, of Boston, county of Suffolk,State of Massachnsetts, have invented an Improvement in Atomizers, ofwhich the following description,

in connection with the accon'lpanying drawings, is aspceification, likeletters on the drawings representing like parts.

This invention has for its object to construct an atomizer; and itconsists in various details of construction, to be hereinafter describedand claimed.

The atomizer herein shown is of the class employing compressed air foratomization, yet some of the details to be referred to are applicable toatomizers of other well -known classes.

Figure l. shows an atomizer embodying this invention. Fig. 2 is a detailto be referred to; Fig. 3, a vertical section of the air-controllingIvalve or eut-off, the air-filter, and the pivoted connector by which.the cutoff is eon- .nected with the outlet-tubo; Fi i, a horizon talsection of the out-let or delivery tube of the atoniizer; Figs. 5 and(3, vertical sections of modified forms of air-filters and couplingsadapted to be connected with the air-tube. Fig. 7 shows in elevation anatomizer supplied with the usual air-bulb and with atomizingnozzlesembodying this invention; Fig. S, a side view of the air-controlling orcut-off valve, shown in connection with an atomizer of a differentclass.

p The air-pump a (see Fig. 1) is of any suitable construction, havingleading from it a pipe, a,whieh pipe leads to and is connected with theair-cylinders b b by branch pipes or serew-tlneadcd nipples radiatingfrom a shell, case, or frame, 1F, which is provided with a four-waycock, h3. The pipes or nipples radiating' .from the shell in oppositedirections have right and left screw-threads which enter collarsfastened tothe cylinders, as best shown in Fig. 2i A gage, b1, isconnected with one of the radiating' pipes or nipples, as shown, todetermine the pressure ot' the air contained in the cylinders.

rl'he air-pipe e leads from the Vfour-way cock b3, its outer or free endbeing firmly wired or attached to a coupling or connection, Q. Thecoupling 2 has a tapering nozzle or end poring prevented by said hub.

tion, 3, which fits t-he taperingl opening 4, 'formed in the lower endof thel air-filter 5; `The coupling 2 has formed on it a flange, 2X, andthe tapering end portion, 3, has formed on it a hub or flange.

A nut, 7, recessed t0 receive the hub or flange on the end portion, 3,is fitted loosely on said end portion, its removal. therefrom be- Thenut 7 is inieriorly screw-threaded, and is thereby adapted to be screwedupon the threaded portion 6 of of the air-filter 5, connecting theair-,tube e with the said air-filter. The nut 7 serves as a union todraw the tapering end portion into the opening 4 to make an air-tightconnection, and yet permit the tube e to be turned or twisted as much asdesired. Instead of this particular form of coupling, a coupling such asshown in Fig. 6 may be employed, it coniprising the coupling f, havingthe flange f', the nutj'g, recessed to receive the flange j" and`ntcriorly screw-threaded to be screwed upon the air-filter 5. In lieuof this form the coupling shown in Fig. 5 may be employed, it comprisingthe coupling t', having the flange i", the nut i2, recessed to receivethe iiange o" and interiorly screw-threaded to be screwed upon theair-filter 5. The air-filter 5 contains cotton or other suitablematerial, held in place by a slitted or foraminous plate, 9.

The air-controlling valve or cut-off comprises the valve-case 10, havingaliole or passage through it, a valve-seat, 12, and avalve, 13. Thevalve 13 is supported by and held pressed against its seat by a spiralspring, 1.4i, seated in a cap, 15, having a hole or passage through it.It is held to its seat by'pressure of compressed air against it also.The valve 13 has an annular groovc,which is filled with any suitablepacking', 17. The valve-stein 1S passes vertically through the case l0,it being connected at its lower end with the Valve 13 loosely orotherwise, as desired, said stem having its bearings in a suitablestuffingbox at the upper end of the valve-case 10. The valve-case 10 isattached rigidly or otherwise to one side of the tube or hollow cylinder19, the passage through the valve-ease 10 communicating with the openingthrough the said tube or cylinder. A bent lever, 20, is pivoted to thetube or cylinder 19 at 21,'the

outer or free end of the said lever 2O beingl l nal bore, and has also aeonieal .tlauge lll,

' upon or over which the usual rubber alr-t.ubt`

bent downward and outward, as at 22, to be engaged by the thumb orlingers ot the oper ator, the said outward bend 22 being"adapted t'oreceive upon or beneath it the linger-or tingers or thumb ol? theoperator, to therebyhold the lever in one or Aits other extreme position, prevent'iugl aeeident'al depression olf the lever, exeept whendesired.

The adjustiiing-serew 23 passes through the upper end of the bent lever20, the end ot Iwhich screw bears down upon the upper end ol thevalvefstem i9. lt will be seen that by depressing the bent leverLOthevalve-sttun IS will be depressed by the adjusting-screw i and open thevalve, and, furthermore, that the extent olf movementol the valvfhst'emmay be determined by the said adjusting-serew, thereby eompensating lordil'lerent length stoms, &e.

lhe valve-ease lll maybe attaehed toeither side ot.' the eylinder i9, sothat the lever iid maybe opta'at'ed willi either the right or lelft handconveniently; but as all rubber tubing sul'tieitaitly heavy to resistpressure ol' eompressed air is inflexible to the extent that whenseeured to any metallie connection having no provision :lor zuljust'menteirelui'ii'erentially it resists sueh movement or atljustw nient.

l have herein shown a eoupling made as deseribed to allow freedom ofmovement ott' the valve-ease on it, so that the said vz'ilve-ease andeylinder may together be turned in whatever position desired to beoperated by one or the other hand. llor these and other reasons to berel'erred to, the eoupling 2, made as de seribeal, is essential. Thetube or eylinderlfl at its upper end has projeeting from it laterally aslightly-t'apering hub or eyliiuler, Q4, having a passage, 25, throughit, which eom munieates with the passage through the tube or cylinderif), said passage 25 terminating at one side ot' the eylinder orlno'ieetion it, A tapering nozzle or eonpling, Lti, isplaeed upon thehub or jl'irojtation il, it being held by a sere'w and nut withsuliieient.- frietion tomaintain its position wherever plaeed, and alsoto torni an air-tight joint.

The nozzle or eoupling 2G has a tlange, 2T, and a nut, 2S, recessed tioreceive the ,liange The nozzle or eoupling 215 has at Vits rear end athumb-bearing, tittagainstwhich the thumb may resti, sueh. position lorthe thumb being most eonvenieut'f,

lt will be seen that the nozzle or eoupling Qt, turning onv the hub i isl'ree to be moved to point in any direct ion desired.

'lhet'apering nozzle oreouplingti is adapted to enter the tube or pipe2li, eonneetied with -or l'orined as a part ol' the air-tube Ilo, andthenut 2S `is interiorly serew-threaded to be turned upon theserew-threaded end oli the said tube 2f), to thereby draw the taperingportion of.' the nozzle 2li into said tube or pipe.

rlhe tube or lnipple 2f) has a t.^i.]f)ering intern i l'rietionaflly onits hub tio oeeuplv any position eonlaet, and proper adjustment is atonee semay be sprung or drawn when Vit is not de- 7o sired to use thetube e and eoupling.

rlhe nozzle 2li, its Vflange 2T, and nut 2S are substantially the saineas the nozzle il, its liange, and nut 7,bel'ore deseribed, it turningdesired.

rlhe air-tubelO,'l1eren shown as bent at. an angle, is at'taehet'l, tothe eap or stopper 25| ot' the jar or v ,ssel 32, said eap or stoppereon taining a suitable paeking, 33.

The air-tube fill Contains the litptid-tuln'i i-ll, whieh extendsdownward at or nearly to the botttnnof theiarorvessel 2id. Aeap,yl-tl,having an opening,l'l, is threaded upon the said tube i3d, havingseated within it lthe washer Ii, and the liquid-tube i-lA has torniedupon or attaehed to ita tlange, t,witl1in said tube liti, and ay spiralspring, 3T, eneireles the liquidtube Eli, one end oli' whieh bez'tr'sagainst. the tiange fili and the other end against the washer 35, seatedin the eap it). -lhe liquit'l-tube Ii-lat its Forward end is Infovided.with the usual atomizing-nozzle, 38, and the air-tube SO is providedwith. the usual spray-nozzle, 30, and as spray-nozzles et' dil'ierentshape and leon tigurat'ion are desiraliile said nozzles are de taehable.

The atomiziiig-tubes (see Fig. el) are oli' the kind in whieh the twotubes are arranged eoneentrieaflly, as deseribed, and in whieh the airoo and liquid eome together between the end ol.'

the inner nozzle, iid, and the inner surlz'tee oli theouternfiizzle,fill. ln this kindol atomizer its pratitieal and sueeessl'ul operationdepends largely upon proper adjustment'` ol' their noz zles to eaehother.

This kind ot' atom izer as usually made does not have its nozzleadjustable, the position otl inner tube being in some eases dependentupon itsI l'rietion against the outer one only, and .in other easesbeing soldered to the outer one at the inner end ol the latter. In suoliatomizers it is dit'lieult or impossible to make sueeesslul use ot' anozzle rotatal'ile bymeans ot' a serew-tluead and designed to dischargesprayin anyolj' the directions to whieh .it may be turned. lVithmyimproved construction, however, it is necessary only to screw thenozzle on until the surfaces, as described, are in cured and'imiintained through all 'remaining revolutions ol' the outer nozzle. Byseeuring the litp'iid-tnbe 3ft in the manner shown it may be removed atany time desired and eleansed or a newtube inserted.

The operator using the atomizer holds the. eontrolling-valve oreut-olli' in"one hand and depresses the lever 2d, ant'llnby connectingsaid valve with the air-tube e by the eouplingI herein shown and`described it maybe 13o turned to present the lever 2O at either Iside,to be operattial by either the thumb or lingers or by either the rightornlet't hand; also, by providing the eoupling or mmneetion 2li betweenthe said controllingvalve and the atomizing-tubes with thefriction-joint herein shown it will be seen that the said coupling maybe turned or pointed in either direction and still subserve the purposedesigned Al'or it.

It will also be seen that the lever .0 may be adjusted to move thevalve-stem more or less, as desired, to thereby control the supply ol'air or to compensatetorvalve-stems ot dil'ferent length.

In Fig. S is illustrated the air-controlling valve and a bottle, and itwill be seen that the said valve may be held closely against the bottleirrespective oli the relative angles ot' the coupling 2G and valve;also, when a bottle of the form shown in Fig. 7 is used and is placed ona table the eoul'iling i, turning on its hub, permits the valve to swingoutward, that the bottle may not be overturned.

It will be seen that many of the features herein describwl are asapplicable to atomizers ot. other classes as to those herein shown .i
